Providing money, roads, education, electricity, and employment to needy people of the world is a noble idea, but it’s like putting the cart before the horse when a billion people don’t have a reliable source of safe drinking water. They are in danger of ingesting typhoid, dysentery, salmonella, diphtheria, E. coli, or cholera. Water treatment plants and long distance pipes are terribly expensive for Third World nations, and even purified water can become contaminated with disease before consumption.
A possible solution: a personal water filter for each person. Danish water purification company Vestergaard Frandsen has developed the LifeStraw® Personal, a small filter that requires no power and can be worn on a string around the neck. There are no moving parts and no maintenance is required. Sip water directly through the LifeStraw® and it removes 99% of waterborne bacteria and viruses. There are several layers inside to filter out increasingly smaller pathogens, then iodine to kill the smallest, and finally charcoal to remove the iodine taste. After use, you blow air back through the straw to clear the filters. A personal filter lasts for about a year’s use. It is not effective against the parasite Giardia lamblia, which is smaller than 5 microns, but the company is working on it.
Vestergaard Frandsen also offers the LifeStraw® Family, which can be used to clean a household water supply. The filter cleaning is just a bit more complicated than the personal filter, but still simple. The family filter should last two years.
LifeStraw® won the Saatchi & Saatchi Award for World Changing Ideas earlier this year, among a growing list of awards and accolades. It is not available at the retail level yet, although many are interested in using it for camping or international travel. Organizations and corporations who want to set up a distribution deal can contact Vestergaard Frandsen. Hundreds of thousands of LifeStraw®s have been distributed so far, much of them shipped to victims of disasters such as the 2005 earthquake in Kashmir and the recent cyclone in Burma. The cost of the personal LifeStraw® is about $3 each, which is too expensive for most of the people who need it. There’s the tragedy, since $3 is about the cost of a morning latte for most Americans.

It can’t be used in salt water, can it?

You can donate LifeStraws as an individual. Click on the Life Straw link and you will see a donate button on the left. A Family Lifestraw costs $15.

only $3! We need to get donating!

I’ve also been impressed with the development of Dean Kamen’s Slingshot and Stirling.

Awesome! Way to invent something useful, life-changing, and life-bettering, Vestergaard Frandsen!

Wow, this is awesome! Something about drinking brown, murky water directly from a straw (even this particular straw) just doesn’t seem settling though. Bravo for the idea however!

They should sell them in wealthier nations for $10 (or whatever) and use the extra money to fund distribution in third-world and disaster stricken areas. There’s a company that makes very cheap personal computers for impoverished areas, and they sell to wealthier people/countries at a higher rate to fund the donations.
As a hiker/camper, I would definitely pay extra for something that’s both really useful and a good cause.

Wow. I never thought I would be in favor of inflated pricing, but that’s a great idea, gib.

I’ve been an avid reader of the Mental Floss and I also have been working directly in humanitarian aid and international development for various non-profits in sub-Sahara Africa in the water sector for many years now – I’d love to offer three thoughts.
The first is the little-known fact that that typhoid and salmonella are the same disease; just different terms for different continents.
The second is that Lifestraw is an amazing piece of technology that has saved thousands of lives and hats off to Vestergaard Frandsen for the design. It’s has amazing applications in emergency relief settings where the ability to instantly reach tens of thousands of individuals is critical for survival. The one organization I worked for purchased containers of these for tsunami relief along with millions of P&G’s PUR Sachets which are another great water purification technology for emergency relief situations.
The third thought is that people often confuse relief work with development work. Development requires sustainable solutions that can be implemented at the local level. With a one/two-year lifespan on a filter, who is going to export these and pass them out to millions of impoverished people year after year? It creates a hand-out mentality and dependency (similar to the welfare trap in the USA). In a development setting, technology should empower communities towards self-reliance. Technologies like the BioSand Filter can be built right in a community and passed on down to grandchildren. That’s sustainability, and that empowers local people with the ability to take charge of their own futures.
On the flip side, the Biosand Filter weighs 300lbs and is made from concrete… it’s not applicable to emergency relief. The lifestraw is and it’s amazing for what it accomplishes. Each has their place and but it requires knowledge of the context and understanding of the long-term consequences to determine the right technology for the right circumstances. There are lots of things that exacerbate poverty, but mostly though, poverty is about building hope and self confidence and changing perceptions of ones-self. If it were just about technology we would have solved poverty a long time ago.

Appropriate technology like Barak Bruerd said can work wonders. Here is one of them.

There was another invention on the dragons den TV show that looked even better than this but at greater cost. With things like this being invested in we could sort this world wide problem out in our lifetime.

if this can’t filter out parasites 5 microns long, there’s no way it can filter out any viruses

If this is, as they say, able to make water drinkable it’s an affordable gift to help lives… To offer the most basic of needs… I truly hope this can do all that’s been promised. I’ve been to many places in Africa, India, Malaysia,KL and seen the need first hand.

Money comes and goes -
The answer is for everyone to do all they can… NOW… because we never know if we can tomorrow.

But does it work on radiated water?
posted by Sam on 5-15-2011 at 2:23 pm
If you haven’t read it yet, read Barak’s excellent post. Barak, you hit the nail right on the head. Ultimately the focus of every non-emergency relief effort must focus on sustainability, while at the same time ensuring that the top priority is ensuring that the community helps themselves, or enabling that. Fantastic post, and this is coming from a guy who never ever comments.

So all viruses (under 1 micron) and most bacteria (under 3 microns) pass through?
posted by Adrian on 6-14-2011 at 2:35 pm
They pass through the filter yes but the article states that the bacteria and viruses are killed using iodine.
posted by Brandon on 6-23-2011 at 11:38 pm
This is an amazing invention. It should be marketed to survivalists and campers and marked up (like it will be anyway) so that the money made above profit goes to buying these for people who need them to live.
Also, why is it that every freaking article I read about things like this have some sort of line at the end stating “And $X is about the cost of the average *something mundane* for an American.” Seriously? It is the same in other developed countries too. Just stop.

With all the millions that the African governemet steals, the least they can do, is buy straws for everyone, and will pay for itself, by saving money on health care and funerals………….

Frank:
Seriously? The African government? I wasn’t aware there was a single government for Africa. And it’s not like the US Government doesn’t waste money — besides defense contractors, we could look at the fact that the US has the highest per-capita rate of prisoners, and over 90% of those are for non-violent crimes (almost 70% for marijuana use alone). That’s without even looking at pork barrel projects.

I hate to sound like a jerk, but seriously, how many hundreds of billions of dollars have been sent to various African countries in the past 30 years?
Hand outs are not the answer

Miller, you’re ignorant and misinformed, and yes, a jerk. Get over your own objective sphere of a first world utopia.
